Application of the Vibration Decay Test to Transmission Line Conductors

Abstract

Application of the vibration decay test to transmission line conductors provides a simple method of evaluating conductor self-damping on laboratory spans. Although special recording methods are not necessary, logarithmic response recorders simplify the data reduction. The procedure can be used to investigate the effects of stringing tension, external damping, and conductor history on conductor self-damping. The prime advantage of the decrement procedure is its simplicity and the ease of data reduction.
